To begin with, take up the phone and go to the main menu. Now look for the button "Settings".
Go to menu, custom on. Looking for "Security" section (or something similar).
Select in the appeared new sub vladochka Phone. Now we need a button "personal data Protection". My phone immediately appears the list of folders that can be password protected: "All", "calls", "phonebook", "Messages", "My files "memory Card", "Calendar", "Task", "Reminder".
Select those folders that we wish to put password, note them and enter the combination of letters and numbers. It is well aware that all passwords from the folders in the phone you need to keep in mind because if you suddenly forget even one of them, access to information will be closed. Have to reset phone to its factory state, and in some cases to "reflash" the phone. In any case, data will be lost. So write down the passwords in a secret book and keep it away from prying eyes.
